Note that when data are collected in Trigger Button mode, the Smart System will emit a beeping
sound after the button is pressed to indicate data collection is taking place.

12.3.2.3 Auto Start
If the Auto Start option is set to ON, after the user presses Run to collect a data line, the system
will automatically boot up and be ready for data acquisition, rather than having the Start button
appear. This prevents the user from having to press the Start button at the start of every new
line. This setting is especially useful when collecting numerous lines as occurs when
collecting grid data. If Auto Start is set to OFF the user must press the Start button to begin
data acquisition for each line.

12.3.2.4 Arrow Offset
Section 12.2.7: P.74 describes the Back-up Arrow that appears when the Smart System is
backed up. The Back-up Arrow allows the user to pinpoint the exact ground position
corresponding to a target response on the data image. The Arrow Offset value is used to change
the physical position that corresponds to the Back-up Arrow. If the Arrow Reference value is set
to the default value of zero (0.0) metres, the Back-up arrow position corresponds with the centre
point of the Noggin.

corresponding to a target response on the data image. The Arrow Offset value is used to change
the physical position that corresponds to the Back-up Arrow. If the Arrow Reference value is set
to the default value of zero (0.0) metres, the Back-up arrow position corresponds with the centre
point of the Noggin.
However, the Arrow Offset value can be changed so that the Back-up Arrow corresponds to a
position at any offset from the centre of the Noggin. For example, setting the Arrow Offset value
to +0.25 metres moves the Back-up Arrow to line up with a position 25 centimetres in front of the
Noggin centre point (on the Noggin 500 SmartCart this roughly corresponds to the front axle).
Setting the Arrow Reference value to -0.25 metres moves the Back-up Arrow to line up with a
position 25 centimetres in behind the Noggin centre point (on the Noggin 500 SmartCart this
roughly corresponds to the back axle). In this way, the Arrow Offset value can be changed to
correspond with any position desired by the user.

One reason the user may want to change the Arrow Offset value is to ensure that the Noggin
does not cover the actual target location. This makes it easier to spray paint a mark or put a flag
on the ground where the target occurs.

Positive values correspond to positions in front of the Noggin and negative values are positions
behind the Noggin. Note that the Arrow Offset value is always expressed in metres regardless of
the settings of the other units.

12.3.2.6 Transfer Rate
Transfer Rate is a variable from 1 to 8 that corresponds to the speed of the data transfer from the
Noggin to the DVL. A value of 8 provides the fastest transfer speed while a value of 1 is the
slowest.
